VNC Thumbnail Viewer is a free program for Microsoft Windows devices that allows you to monitor multiple remote devices in one location.

If you are working in a network environment where it is essential to monitor selected computer systems you may want to give VNC Thumbnail Viewer a try.

It is a great remote desktop software for teaching environments, where it is essential to know what the students - or other users - are doing on their computer systems.

VNC is a very popular software that can be used to view a remote system's desktop. It's main limitation is that it can only be used to view one system at a time.

VNC Thumbnail Viewer has been created to overcome this limitation. It is a remote program that displays a real-time thumbnail image of remote computers on a server system.

The software program comes with two components: A server program that has to be installed on all remote computer systems as it is being used to send screenshots of the desktop over the network to the viewer app.

The viewer component needs to be run on another computer system. It displays the screenshots that are sent over the network.

So, what you get in essence is a view of all systems that are online and on which the server program is running on.

The installation of VNC Thumbnail Viewer is outlined below:

  • Start VNC Server on all remote computer systems. You also need to ensure that a VNC client like UltraVNC or TightVNC is used on the system.
  • Start VNC Thumbnail Viewer on another computer system.
  • Connect it to the remote computer systems by entering their IP or Hostname, port number and server password. The window will automatically scale depending on the number of connected vnc servers
  • A double-click will will open that server in a new window giving the admin control of the keyboard and mouse

The VNC Thumbnail Viewer application is available for Windows, Linux and OS X. Note that it is programmed in Java, so make sure Java is installed on the device before you install the application.

The thumbnail view may be too small to identify what is going on, which is why you can double-click on any session displayed in VNC Thumbnail Viewer to get better control of it.

Note: The last version of the application has been published in 2008. It appears as if the program has been abandoned by its developer. It may still work however. The developer has posted links to other solutions, but only the paid solutions appear to have been updated regularly.

    Great article regarding VNC Remote Desktop Software used for remotely accessing and controlling computers. Additionally, one can even consider deploying on premise remote support appliance such as Bomgar or RHUB appliances in order to remotely access computers from anywhere.
